$1.25 Undermount mudflap test

So I finally decided to test the idea ... does an undermount mudflap work instead of a fender? So I went to the dollar store and bought myself a cheap dustpan with a silicone edge - $1.25 at the dollar store. I cut off the edge and taped it underneath the board with the silicone edge tight against the tire. Rode it in gravel for a test and I think the idea can work! As the tire is curved we'd want to have the edge shaped to follow the curve of the tire (which means I'll need to find something with a wider silicon edge... maybe a squeegie?)... but as you see in the picture below it is able to trap stuff in the middle of the tire; and only at the sides is the gravel getting thru.

Right now it's attached ghetto-style with electrical tape, but since the rotation of the wheel is pushing the "mudflap" up anyways, it shouldn't be too much of a concern to keep it on. Will keep trying with different materials... but I think this could be a less conspicious option to the fender.

I thought about the brush which would be easier to shape but it would be pretty thick whereas a squeegee type silicon edge can be quite thin. The only issue is that I need to find something that I can shape to the tire curves. Might actually look into buying an actual car mud flap and cutting it to shape. ..

@njcustom what if you integrated it somehow on the rail covers. .. slide on the covers which include mudguards at the right spot. This solves how to attach the mudguards onto the board without tape or glue.
